Latest Patents
One of Lars Gillberg's latest patents is a method of treating residual acid from the production of chlorine dioxide. This innovative method involves adding a compound containing iron to the residual acid, which reacts to form a product containing iron in trivalent form. Specifically, ferrous sulfate is added, which, upon oxidation, reacts with the residual acid to create ferric salt. Additionally, oxidants such as sodium chlorate, sodium hypochlorite, hydrogen peroxide, or an oxygen-containing gas are incorporated into the process.
Another significant patent by Gillberg is a method of purifying sewage. This method is designed for sewage systems that include a toilet. It involves adding a precipitant for the precipitation of phosphates and binding organic substances. The precipitant is selected from iron salts and aluminum salts, such as sulfates, chlorides, and nitrates, and is intended to be flushed with water in the toilet bowl during flushing. The sewage from the toilet is directed to a sludge separator through an outlet pipe leading to the lower part of the separator.
